Title: Improvements in or relating to Pulse Analysing and Counting Arrangements
Inventor: KANDIAH KATHIRKAMATHAMBY
IPC: G01T1/15
Filed: 1965-08-13
Abstract: 1,153,574. Radioactivity counting arrangements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Aug.25, 1966 [Aug.13, 1965; Dec.6, 1965], Nos.34885/65 and 51724/65. Heading G1A. An arrangement for handling pulses from a nuclear particle detector comprises an input capacitor (which may be the detector) across which signal pulses are developed in response to detected particles, a light reponsive semi-conductor connected so as to apply discharging current to the capacitor and a light emitting semi-conductor arranged to illuminate the light responsive semiconductor with a flash of light in response to an energizing signal. Pulses from a solid-state capacitor type of detector 10 due to the incidence of nuclear particles or γ-rays are fed via a capacitor 14 and a gate 15 to an integrator 18. Normally the gate 15 and a switch 17 are both closed so that the input to the gate is held at a substantially constant potential despite drift in the detector output. When a pulse occurs the discrimator responds to open gate 15 and allow the pulse to pass to integrator 18. The discriminator then sends a signal to a discriminator 12 which samples the output of amplifier 11 and energizes a GaAs diode 23 to produce a propotionate amount of light. Some of this light is received by a photo-diode 22 which sends a corresponding pulse of current to the detector 10 just sufficient to discharge it. At the same time the pulse shaper 13 is inhibited by a signal from discriminator 19 so that the gate 15 is not opened in response to the discharge pulse from detector 10.

Abstract: 1,129,011. Stop motions. T.M.M. (RESEARCH) Ltd. 11 Feb., 1966 [28 Feb., 1965], No. 52528/64. Heading D1D. A stop motion for a textile machine in which slivers are processed, comprises a photoelectric cell, means for creating a light beam to fall on the cell, a feeler arranged normally to bear against the sliver and biassed to move so as to interrupt the beam when the sliver breaks, and a circuit for generating a stopmotion signal in response to a change in the resistance of the cell resulting from the change in its illumination, the feeler being pivotally mounted on a support and is displaceable to a position clear of the sliver during normal processing. The feeler may only 'partly interrupt the beam; it may interrupt it momentarily to produce a momentary signal; or it may move to a rest position to produce a continuous signal. The invention is described as applied to a speed-frame where the upper rollers 14, are arranged in pairs, each roller co-operating with a fluted boss on a continuous lower roller 12. The spindle are arranged in two banks; of each pair of rollers, one supplies a spindle in one bank and the other a spindle in the other bank. Each pair of rollers is carried by an arm 16 having a cover 20; on each cover is a bracket 21 carrying a bar 22 on which are slidably mounted two clips 24 to each of which is pivoted a feeler 25, 26 of channel form with the side walls widening towards the free end. The feelers can be raised manually to a position 25<SP>1</SP> where they are inoperative. The photo electric cells are arranged in oppositely-facing pairs below the sliver paths, and so disposed that when a sliver breaks, the feeler, falling by its own weight, obscures the cell when it assumes a rest position, or momentarily obscures it in passing to that position. AC- and DC-fed transistorized circuits are described whereby the stop motion is operated when a circuit is triggered to energize a relay to close contacts in a control circuit for the main driving motor.

Headings F1G and F1J. The invention relates to an air intake structure for a combined gas turbine jet engine and ram jet engine, air passing through a central duct 1 to the gas turbine engine and through an annular duct 2 which is disposed around the central duct, to the ram jet engine. A streamlined structure is disposed at the inlet to the central duct and comprises two parts 5, 6, one part being movable relative to the other part in such a manner as to shut off the air supply to the gas turbine engine. The intake structure comprises a lower portion 3 which is fixed, and an upper portion 4 which is pivotally mounted about the axis 0, Fig. 1, the upper portion being movable by means of an actuator 25; the parts 3 and 4 define an intake which is substantially rectangular in form at the forward end in the plane III-III and which merges to circular form at its rearward end in the plane IV-IV. An inner part 5 is rigidly secured to the movable part 4 by means of struts 7, 8, the part 5 comprising a circular ring portion 10 at its rearward end, the ring portion having a partspherical surface which co-operates with a corresponding surface on the wall 11 which forms the boundary between the central duct 1 and the annular duct 2. The lower surface of the part 5 is cut away as indicated at 9. A further part 6 is mounted within the part 5 for angular movement relative thereto, the part 6 having a circular ring portion which is supported within the ring portion 10 of the part 5 by means of a bearing 13. The part 6 is rotatably supported within the part 5 at its forward end by means of a bearing 12. The ring portion of the inner part 6 has a gear sector 14 which engages with a fixed bevel pinion 15, the arrangement being such that as the Intake part 4 and so the part 5 is moved about the pivotal axis 0, so the part 6 will be caused to rotate with respect to the part 5 about the axis X-Y so that the air intake to the gas turbine engine is open as indicated in Fig. 1 or is closed as in Fig. 2, air in the latter case passing only to the annular duct 2 of the ram jet engine.

Abstract: 1280906 Multiplication by squaring BURROUGHS CORP 6 Nov 1969 [7 Nov 1968] 54421/69 Heading G4A An electrical binary digital squaring device comprises an input register for receiving the operands, a plurality of gates connected to the input register to produce a plurality of partial products, a one step adder connected to add together in parallel the partial products, means connected between the gates and the adder to simplify the products before addition, and an output register connected to the adder to store the squared product. Multiplication of two numbers a, b is effected using the equation ab = [(a + b)/2]<SP>2</SP> - [(a - b)/2)<SP>2</SP>. Digital electric arithmetic units receive the binary operands a, b to be multiplied, calculate (a + b)(a - b), divide each by two by shifting one place right, feed [(a + b)/2][(a - b)/2] into squaring units where each is squared in parallel, and then subtract the two to produce the product ab. Each squaring unit is formed of simple AND gates (Fig. 3, not shown) or conventional adders for each order of the product, the partial products being added in one step addition. One arithmetic and one squaring unit can perform both squaring operations in sequence (Fig. 12, not shown). Where one operand is odd and one is even the last (M) bit of (A + B), (A - B) will be set to one and the second operand added to the product (Fig. 12, not shown). Other features include floating point operation and forming a single precision product i.e. a 10 x 10 bit multiplication gives a ten bit product by dropping the lowest ten bits of the twenty bit product. The product may also be calculated using the related formulae or

Headings G4B and G5G. A planisphere includes at least two concentric discs rotatable relative to one another, the discs being a sky map disc 12 having indications of the heavenly bodies representative of the celestial sphere thereon and an annular date scale 42, and a local time disc 16 having a local time scale 64 around its periphery and a sun indication 75 at the noon position; a mask 14 pivotable about the axis of rotation of the discs and including a transparent portion 46 the edge 48 of which represents the horizon of an observer at a predetermined latitude (as shown 42‹ N.); a line 36 representing the meridian of an observer on the transparent portion; and a reference rule 26 pivotable about the axis of rotation of the discs and positioned between the mask and the sky map disc. The planisphere also includes a standard time disc 18; a navigation disc 20 having a number of scales for navigation purposes; and 28-day and 32-day moon phase discs 22, 24. The reference rule 26 is transparent and has an indicating line 70 thereon. The local time disc 16 further includes representations 66; 67 of the 28-day and 32-day moon phases. To demonstrate the portion of the heavens which may be observed at a particular time on a particular date, the sky map disc 12 is rotated until the particular date on the scale 42 is adjacent the sun indication 75. Then rotation of the mask 14 until an indicator line 58 indicates the time of day on the scale 64 will expose through the transparent portion 46 the desired view. To find the rising and setting time of the sun on a particular date the sky map disc is rotated to bring the date adjacent the sun indication. The mask 14 is rotated until line 58 is aligned with the neon point on the time scale 64. The rule 26 is rotated to fix the point at which the meridian representation 36 intersects the ecliptic 40. The mask is moved clockwise or anticlockwise until line 48 meets the fixed point and then the time of setting or rising indicated by the line 58 can be read off from the scale 64. Other uses of the planisphere include finding the rising and setting times of any other celestial body; the declination and altitude of the sun; the meridian angle of any celestial body; and moon phases.
